SHIELD FOR OVEN BACKS.

Application filed October 11, 1922. Serial No. 593,807.

To all whom it may concern Be it known that I, HENRY KIELBERG, a citizen of the United States of America, and resident of Martins Ferry, county of Belmont, and State of Ohio, have invented certain new and useful Improvements in Shields for Oven Racks, of which the following is a specification.

This invention relates broadly to ovens of knock-down type. and more specifically to a rack embodied heat deflector for such ovens. I

The primary object of the invention is to provide a novel construction of pan-supporting rack for ovens of theknock-down type exemplified in my co-pending, or companion, application for patent, Serial. No. 593.805, said rack embodying means whereby heat and flame from stoves or burners upon or over which the oven is mounted are deflected from pans or other vessels superposed upon the rack for preventing the burning of the contents of such pans or vessels.

A further object of the invention is to provide a rack of the character mentioned the parts of which may conveniently be partially disassembled to permit of its being packed in small space, as for storage or shipment, and as readily assembled when occasion requires.

In describing the invention in detail, reference is herein had to the accompanying drawings, in which- Figure 1 is a partial vertical section of an oven showing my present invention mounted therein;

Figure 2 is an enlarged top plan View of the invention; and

Figure 3 is a reduced sectional elevation of the same, the section being taken on line 33, Fig. 2.

Referring to said drawings, 1 indicates the front wall, 2 the rear wall, 3 the bottom, 4 an end shield plate, and 5 the door opening of an oven of the type disclosed in my companion application, Serial No. 598,805, hereinbefore referred to.

The opposite shield plates 4 of the oven are designed to have seated on suitable supports, as inwardly pressed ledges 6 formed therein, the opposite ends of one or more horizontal racks whereon baking pans or other cooking vessels may be supported within the oven, said'racks being insertible and removable through the door opening 5 in the front wall 1 and thence slidable to and from seated positions on said ledges 6.

Said rack, or the lowermost rack if and when a plurality thereof are employed, is of substantially rectangular form and comprises an outer frame 7, preferably of approximately U shape and formed of a single length of heavy wire, and a plurality of parallel bars or rods 8, also preferably made of wire, disposed transversely of said frame and having their ends rigidly mount- 'ed upon the parallel end members of the latter. Y

Permanently carried by said rack is a sheet metal plate 9 which, in end elevation, presents a slight downwardly bowedcurvature, The front and rear longitudinal edges of said plate are curled downward. to form hooks 10 and 11 which overlie and are permanentlyengaged with rack bars 8 located adjacent to the front and rear portions, respectively, of the rack and the bowed body portion of said plate underlies those rack-bars which lie intermediate the bars to which said hooks are attached. Said plate 9 serves as a shield whereby heat admitted through the apertured bottom 4 is deflected and prevented from directly coming into contact with the bottoms of baking or cooking vessels mounted upon the rack.

Supplementing the shield 9 is ashield or baffle 12, also formed of sheet metal, which is supported at a suitable distance below said shield 9, thereby to form an intermediate air space-13, said baflie being designed to deflect heat and flame rising through the apertured bottom i from the stove or stoveburners over which the oven is seated. Said bafile has the main body thereof of downwardly bowed form in end elevation, while the front and rear edge portions thereof are disposed approximately upright, as shown at 14, and terminating in outwardly turned hooks 14c adapted to be sprung into seated baffle-supporting relation'to the same bars 8 by which the shield 9 is supported. To facilitate theintroduction of said hooks 14L in supporting engagement with said bars 8, the hooks '10 and 11 of the shield 9 are made slightly larger interiorly than the diameters of said bars, as shown in Fig. 3, thereby to allow the terminal edges of the hooks 14 to be received within said hooks 10 and 11 in partially overlying relation to said bars.

The baflle 12 may be sprung for withdrawing its supporting hooks from engagement with the rack, as when the structure is to be. packed in minimum space for storage or shipment.

From the foregoing, it will be evident that heat and flame rising within the oven will be deflected by the baffle 12 and prevented from coming directly into contact with the bottoms of vessels resting upon the bars of the rack. Further, heat radiated upward from the baffle will be deflected by the shield 9, thus additionally protecting the bottoms of such vessels and preventing burning of the contents of the latter. Heated air from the air space 13 unobstructedly escapes from the open ends thereof.

The area of the space occupied by the battle and shield is materially less than that of the rack and, arranged as shown in the drawings, a considerable open space is provided adjacent to the front, rear and ends.

of the oven through which heat may rise unobstructedly. It will be understood, however, that the dimensions of the battle and shield, or either thereof, relative to the dimensions of the rack may be varied to any suitable extent.

lVhat is claimed isy 1. The combination with an oven rack embodying a frame and a plurality of cross bars carried by said frame, of a sheet metal heat-deflecting member attached to and disposed mainly in underlying relation to said rack, and a second sheet metal member depending from said rack and underlying the first mentioned member at a distance from the latter to provide an intermediate air space.

2. The combination with an oven rack embodying a frame and a plurality of cross bars carried by said frame, of a sheet metal heat deflector having hooks formed on opposite edges thereof, said hooks being attached to bars of said rack adjacent opposite sides of the latter, said deflector being bowed downwardly to underlie the rack bars lo cated intermediate those to which its hooks are attached, and a second sheet metal deflector detachably carried by said rack at a suitably spaced distance below the first 1nentioned deflector.

3. The combination with an oven rack embodying a frame and a plurality of cross bars carried by said frame, of a sheet metal heat deflector having hooks formed on opposite edges thereof, said hooks being attached to bars of said rack adjacent opposite sides of the latter, said deflector being bowed downwardly to underlie the rack bars lo cated intermediate those to which its hooks are attached, and a second sheet metal deflector located at a suitable distance below the first mentioned deflector, said second deflector having hook terminals adapted to be attached to and detached from bars of said rack by springing the metal of said second deflector.

4. The combination with an oven rack embodying cross bars, of a sheet metal shield of downwardly bowed form disposed with the body portion thereof in underlying relation to said rack, said shield having clownwardly curled hook-like terminals on opposite edges thereof disposed in overlying engaging relation to bars of said rack located adjacent to opposite sides of the latter, and a resilient sheet metal bafiie having the body portion thereof located at a suitably spaced distance below said shield and having approximately upright opposite edge portions with outwardly facing hook terminals. said shield being adapted to be sprung to and from a position in which its terminals assume seated baflle-supporting relation to confronting faces of wars of said rack.

In testimonywhereof, I my signature in presence of two subscribing "itnesses.
